You can move among your folders by using the navigation buttons in the toolbar and the icons in the Nautilus window.
Try this: Using your home folder as a reference point, navigate your hard disk:
To view your home folder, click the Home button.
To move to the folder that contains your home folder - that is, to move one folder up in the hierarchy - click the Up button.
To return to the home folder, click the Back button.
To view the contents of any folder, double-click its icon (normally a folder icon).
If you think that the contents of a folder have changed while you've been viewing it, click the Refresh button to update the information.
To stop an item from loading, click the Stop button.
